Structural Bone Graft With Wiring for Spine Fusion in Children

  • Interlaminar graft with sublaminar wiring: These grafts are also known as the Gallie-Sonntag or Brooks-Jenkins techniques (4,11,52).These fusions can span multiple levels.
  • External orthosis: An external orthosis is needed with this type of fusion to minimize movement during the fusion formation (12).
  • 18 months to 3 years: This type of fusion is useful for children from 18 months to 3 years in age.
  • Wire pull-through: When the lamina is only 1–2 mm thick, the wire may pull through the lamina or occiput, resulting in fusion failure.
